The lawyer for Kenosha killer Kyle Rittenhouse fumed that he was “going to take Jack Dorsey’s ass down” after Twitter blocked him as he tried to raise money for his client.

L. Lin Wood accused the Twitter CEO of censorship and said he would sue the social media giant for locking down his account for nine hours Tuesday.

“I’m going to take Jack Dorsey’s ass down,” Wood told Fox News. “He has been abusing the First Amendment of this country for his own agenda.”

“I knew they were going to censor me because I’m sending a message of hope,” the lawyer said. “I’m sending a message of truth. And I’m sending a message that Kyle Rittenhouse is innocent.”

Wood, who has nearly 138,000 followers on Twitter, said he was blocked from tweeting for several hours on Tuesday for violating the company’s guidelines — receiving a message that he was “glorifying violence” when he sought to raise money for his client’s legal fees.

It was unclear what specific language Twitter took issue with.

Wood maintains he’s been careful to abide by the company’s rules. He said Monday that more than 11,000 donors had raised $605,000 for Rittenhouse’s legal defense thus far.

Several hours later, the account was reinstated and the company said it had been “incorrectly actioned,” Twitter told Fox.

The company declined to comment further when contacted by The Post on Wednesday.

Rittenhouse, 17, is facing intentional homicide charges for the Aug. 25 shooting death of two protesters in the Wisconsin city and the wounding of a third. The teen was part of an armed group in the city to protect local businesses from looters.

The lawyer has said Rittenhouse acted in self-defense.

Violent protests broke out in Kenosha following the police shooting of Jacob Blake, a black man who was shot in the back by police and may be paralyzed.
